FUEL TANK `Filed Feb. 2o, 1941 2 sheets-sheet 2 1 Hok INVENTOR BY MW/W/m l ATTQRNEY.

Patented Jan. 5, 1943 UNTEn STATES i' T E T OFFICE This inventionrelates to fuel tanks and particularly to tanks adapted for carryingextra fuel for small motor boats and embodying means for facilitatingthe transfer of a mixture of lubricant and fuel to the regular fuel tankassociated with the motor of such motor boats.

An object of the-invention is to provide a tank of the type indicatedwhich will afford greater convenience in use, avoid loss of fuel intransfer to the regular tank and facilitate delivery of a thoroughmixture of fuel and lubricant. A further and more specific object is toprovide improved means for mixing fuel and lubricant. A further objectis to provide improved filter means and a novel combination of mixingand filter means. A still further object is Ithe provision of compressedair fuel ejection through such filter means.

Other and more limited objects will be in part apparent and in partpointed out in connection with the accompanying drawings, wherein Fig. 1is a central vertical section taken through a device embodying theinvention; Fig. 2 is a top plan view corresponding to the line 2-2 ofFig. 1; and Fig. 3 is a horizontal section corresponding substantiallyto the line 3--3 of Fig. 1.

Referring now to the accompanying drawings, the numeral I indicates atank or receptacle of generally cylindrical shape having a closed bottomwall I I and a dome shaped top wall I2. The top wall I2 is providedcentrally with an enlarged opening i3 having an upwardly and outwardlyextending bead I4 modified at its edge to receive a closure I5. Theclosure I5 is removably connected to the bead i4 by any usual type ofseparable connection. A gasket I6 composed of de-V formable material isinterposed between .the upper surface of the bead I4 and a lower surfaceI1 of the closure I5.

In the receptacle I0 and projecting outwardly through the openingl3 is aperforated tube I8 which carries at its lower end perforated baiiieelements I9 and 20 which are supported byplates 2| extending between thebaflie elements I9 and 20 and plates 22 extending above the baffleelement I9. The plates 2| and 22 are sealed or otherwise suitablysecured to the tube I 8. By reason of fact that the tube I8 extends atall times outwardly .through the opening I3, it is possible, when theclosure I5 is removed, to grasp the upper end of the tube I8 and therebyutilize the assembly consisting of such tube and baffle or agitatingelements I9, 20 and 2I for the purpose of mixing, agitating or stirringIthe contents of the receptacle I0.

Sealed to the closure I5 is a conduit 23, the outer end of which carriesa flexible tube 24 and the lower end of which carries a filter assembly.The filter assembly consists of an upper filter holding disk 25permanently attached to the conduit 23 and carrying an enlarged tubularelement 25 enclosing the filtering element 2l. The conduit 23 isimperforate above the disk 25 and is perforated therebelow. rihreaded onthe lower end of the conduit 23 is a second filter holding disk 28, Ithefilter 2l, held between the elements 25 and 28, being of cylindricalshape and received in circular grooves in the elements 25 and 28.

Attached to one side of the receptacle I0 is an air pump 25 having itsdelivery conduit 30 connected through a check Valve 3l to the interiorof the receptacle I0. Communicating at top and bottom with thereceptacle Iii is a gauge 32 which is composed of transparent materialand preferably is graduated, so as to form a means of determining theamount of liquid in the receptacle.

A shield 33 covers the gauge 32 and protects the same from mechanicalinjury. A shield 33 is provided With openings through which the glasselement 32 can be seen. Y

In operation, the desired amount of lubricating Fluid may be introducedthrough the tube I8 when the closure I5 is removed, and then a desiredamount of -gasoline or similar fuel is introduced, the gauge 32 beingused in each case, if desired, to measure in the correct amount. Theclosure is then placed in position, the deformable tube 24 being closedoff as by valve or clamp (not shown). When it is desired to transfer theuid into the regular motor fuel tank, or at an earlier time not longenough to allow excessive stratification, the closure i5 is removed andthe contents agitated by means of the tube I8 and the 'baiiies carriedthereby. rlShe closure i5 is then replaced, the tube 2d is introducedinto the receiving opening of the regular motor tank and air pressure isbuilt up within the receptacle It by operation of the pump 25. Fluidpasses under the influence of such air pressure into the motor fueltank. When sufficient fluid has been transferred, the tube 24 is closedby means of the clamp or valve (not shown) and the pressure is releasedfrom the receptacle IIJ by means of a relief valve 34. The flow of fluidunder the influence of the air pressure is through the perforations inthe tube I8 and into the open lower end of the sleeve element 26, thencethrough the filter element 21 and the perforations in the lower end ofthe conduit 23, and upwardly to the point of discharge through the tube24.

I'l-l will be obvious from the foregoing that I have provided a devicewhich is well adapted for its intended purpose, and while I have shownand described the present preferred embodiment of my invention, I wishit understood that numerous variations are possible within the scope ofthe invention, and I do not desire to be limited except in accordancewith the scope of the appended claims and the requirements of the priorart.

Having thus described my invention, what I claim is:

1. A fuel tank comprising, in combination, a receptacular element having'an opening in the Cil normally upper Wall thereof, `a perforated tubemovably received in and extending through said opening and carryingmixing means thereon, closure means closing said opening and with saidreceptacular element completely enclosing said tube, a conduit sealedthrough said closure means, and extending downwardly within said tube.

2. A fuel tank of the class described comprise ing, in combination, areceptacular element having an opening in the normally upper wallthereof, a perforated tube movably received in and extending throughsaid opening and carrying mixing means thereon, closure means closingsaid opening and with said receptacular element completely enclosingsaid tube, a conduit sealed through said closure means, extendingdownwardly within said tube and carrying a lter inwardly of saidclosure.

3. A fuel tank of the class described comprising, in combination, areceptacular element having an opening in the normally upper wallthereof, a perforated tube movably received in and extending throughsaid opening and carrying mixing means thereon, closure means closingsaid opening and with said receptacular element completely enclosingsaid tube, a conduit sealed through said closure means, extendingdownwardly within said tube and carrying a 'lter inwardly thereof andwithin said perforated tube, adjacent to the lower end thereof.

4. A fuel tank of the type described, the same comprising, incombination, a receptacular element having an opening therein, a closurefor said opening, a filter carried by said closure, a stir-rer in saidreceptacular element accessible for manual manipulation when saidclosure is open and inaccessible when saidclosure is closed, a conduitsealed through said closure `and. 'connected to said filter and meansfor forcing fuel through said filter and conduit to "the 'outside ofsaid tank.

5. A device according to claim 4 wherein said last mentioned v'means isan -air pump.

6. A device according to claim 4 wherein said stirrer includes a tubeextending through said opening and receiving said filter when saidclosure is in closed position.
